There are two slightly different versions of this card. One intended
for use in A4000 machines and another which was intended for use in
A3000 machines. It is not known what the exact differences are, but
perhaps the A3000 version does not require the infamous INT-2 fix or
the A3000 may use lower profile SIMM slots due to height restrictions.
The card contains two expansion connectors, one is used for adding the
additional RAM board whilst the other was intended for local 32bit
expansions. GVP has planned to release a SCSI-II controller for this
expansion port but it appears that no local expansions were ever made
